ADOLPH T. SMITH, OF NEIV YORK, N. Y.

TIP FOR ELECTRIC GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 292,374, dated January 22, 1884.

Application filed July 26,1883. (No model.)

To (LU wit/m1. It may cancer-72 Beit known that I, ADOLPII T. SMITH, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Electric GasBurners, of which the following is a specification.

This invention relates to tips for electric gas-burners; and it has for its object to provide atip with an electrode or electrodes, and means whereby such electrode or electrodes are effectually insulated from the metallic pillar of the burner and the spark prevented from jumping from the charged electrode to the pillar.

To such end my invention consists in a tip made of a non-conducting material provided with an electrode or electrodes, and a laterally-projecting guard-flange at a point below the electrode or electrodes.

This invention is illustrated in the accompanying drawings, in which Figure 1 is a side view, partly in section, showing the tip in position on a burner. Fig. 2 is a longitudinal section, showing a modification.

Similar letters indicate similar parts.

The letter A designates the body of the tip; B, the electrodes, and G the guard flange. Said tip is made of lava, or any other material suitable i'or a gas-burner, and which is a non conductor of electricity, and the electrodes B pass through the tip at the proper places to take the required positions relatively to each other and the orifices of the tip, they being bent at the lower ends to form the usual loops, D, to receive the electrical conductors. Said passage of the electrodes B through the tip can be accomplished in two ways'namely, by embedding the same in the tip in the process of its manufacture, or by placing the same in suitable holes formed in the tip-and it will be seen that by said arrangement of the electrodes they are firmly held in position on the tip without the use of any extraneous fastenings. In the example shown in Fig. l the tip is provided with a shoulder, E, through which the electrodes pass, while in the example shown in Fig. 2 said shoulder is omitted, and the electrodes pass diagonally through the tip. The guard-flange G is formed at a point below the electrodes, it being about midway between the upper and lower ends of the tip, and by its means the electrodes are effectually insulated from the metallic pillar of the burner; or, in other words, the spark is prevented from jumping from the charged electrode to the pillar, due to the large superficial area imparted to the tip by the flange. Said guardflange O is used especially when the gas is lighted by static or induced electricity, in distinction from a galvanic current, which latter does not require the use of the flange.

In some cases, as when single gas-burners are lighted by a galvanic current, one of the electrodes may be omitted, it being replaced by a movable electrode operated either automaticall y or mechanically.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

A tip for electric gas-burners, made of a non-conducting material, provided with an electrode or electrodes, and also provided with a guard-flange at a point below the electrodes, substantially as and for the purpose described.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
